ThirtySix

Thirty-six is the integer that follows thirty-five and precedes thirty-seven. In numerals it is written as 36, and in words as thirty-six. The unhyphenated form thirtysix appears mainly in branding or domain names.

In mathematics, 36 is a composite number with divisors 1, 2, 3, 4, 6, 9, 12, 18, and 36. Its prime factorization is 2^2 × 3^2. It is a perfect square (6^2) and a triangular number (the 8th). It equals 9C2 as well.

In science, atomic number 36 corresponds to Krypton, a noble gas used in lighting, signage, and inert shielding gas in welding. Krypton is colorless, odorless, and occurs in trace amounts in the Earth's atmosphere.

Culturally and historically, thirty-six appears in several contexts. The art series Thirty-Six Views of Mount Fuji by Hokusai is widely acclaimed. Nevada joined the United States as the 36th state in 1864, and Lyndon B. Johnson was the 36th president. The 36th parallel north is a notable geographic line.

In games and measurement, there are 36 possible ordered outcomes when rolling two six-sided dice, and 36 inches equal one yard.

In computing, some historical architectures used 36-bit words, notably the DEC PDP-10 line.

Notes: the standard English spelling for the number is thirty-six; thirtysix is occasionally used in branding but not typical in prose.
